Unveiling the World's Most Valuable Collectors' Items

30. Ercol Furniture (Original Price: $1,000-$5,000* Worth Today: $500-$2,000*)

Ercol is a group of talented British furniture designers known for creating stylish and modern pieces that can elevate any room. Today, you can find their showroom, office, and factory in Buckinghamshire. If you happen to own a piece of Ercol furniture, consider yourself lucky because it can fetch you thousands of dollars, even when reselling.

Identifying an authentic Ercol piece is fairly straightforward. Look for a badge, label, or stamp that indicates the year it was made. If your furniture dates back to the 1950s to 1970s, you'll find a small blue-and-silver square label. In recent years, Ercol has been using contemporary centenary logos featuring their iconic lion as their maker's mark.
